No capitalists own other people's labour. Workers labour time is owned. You'd know this by comparing pay packets and noticing the discrepancy in reward or by seeing that unions exist, or that musk isn't actuall yworth billions more than you. If people were rewarded hard work and hard labour, most women in africa would be billionaires. But they arent, because thats how capitalism works: it exploits everyone downward forever until there is on gazillionaire left.
